SYHINGE-NOZZLE.

SPECIFICATION forming part of Letters Patent No. 777,182, dated December 13, 1904:.

Application filed March 21, 1904- Serial No. 199,258. (No model.)

To all whom, it may concern:

Be it known that I, HARRY M. CLARKE, a citizen of the United States, residing at Atlanta, in the county of Fulton and State of Georgia, have invented a new and useful Syringe-Nozzle, of which the following is a specification.

This invention relates to syringe-nozzles, and has reference more particularly to nozzles for vaginal syringes.

The principal object'of the invention is to provide an improved syringe-nozzle by means of which effectivedilatation of the vagina may be obtained andthe folds of the lining membrane completely smoothed out when the nozzle is introduced.

A further object of the invention is to provide a syringe-nozzle so constructed that con tact of the end thereof with the soft parts at the inner end of the vagina will not cause the obstruction of the duct carrying fluid into the canal nor prevent the return-flow of the liquid through the outer shell of the nozzle.

IVith objects above mentioned and others in View, as will appear in the further description of the invention, the same consists of the improved syringe-nozzle hereinafter fully described and claimed, and illustrated in a preferred. form of embodiment in the accom pany-' ing drawings, forming part of this specification, it being understood that changes in the form and proportions of the elements exhibited may be made without departing from the spirit of the invention or sacrificing its advantages.

In the drawings,Figure1 is a view of the nozzle in longitudinal section. Fig. 2 is a front end view. Fig. 3 is a diagrammatic view showing the nozzle in operation.

Referring to the drawings, in which corresponding parts are designated by similar characters of reference, 1 designates the outer shell of the nozzle, which may be made of any suitable material-such as vulcanite, glass, metal, or celluloid. The shell 1 is preferably of oval or elliptical cross-section, and at the rear or outer end it is flared to present a shield 2 for contact with the vulva. The forward or inner end of the shell 1 is in the form, generally speaking, of a cone, having the base disposed at a very oblique angle to the ax1s and having a rounded or blunt apex 3 considerably to one side of the axis of the shell. Theconical forward end of the shell is provided with a keyhole-shaped opening having its eye 4 disposed at the apex of the conical end and its slot 5 extended to the most remote point on the periphery of the conical end of the shell.

In the interior of the shell a tube 6 is firmly secured with its forward end in registration with the opening TL in the apex of the cone at the forward end of the shell. The tube 6 may be rigid or flexible, as may be preferred, and may be attached to the shell along all of one side, as shown, or may be secured at its forward end only. In all cases, however, the tube 6 will be so formed at its rear end that it may be easily attached to the delivery-tube of a syringe, preferably of the fountain type.

Syringe-nozzles of the construction above described will of course be made in different diameters and lengths to correspond to the dimensions of different vaginal canals, and in the use of such nozzles it is desirable to employ one of such diameter that it will effect the complete dilatation of the canal. Owing to the form of the forward end of the nozzle it may be readily introduced without causing discomfort to the patient, and when in the position indicated in Fig. 3 the apex of the forward end of the nozzle is disposed in the culde-sac posterior to the 0s uteri, so distending the cul-de-sac and insuring the effective action of the cleansing 'iiuid upon its surface. This action of the nozzle, which is due chiefly to the eccentric location of the apex of the forward end of the nozzle, is of special importance on account of the tendency of vaginal secretions, menstrual discharges, and other materials to accumulate in the culdesac.

The peculiar form of the forward end of the nozzle makes it very eifective in cleansing all around the os uteri, as the rotation of the nozzle in the vagina will cause the apex to describe a circle about the 0s and distend the fold in the membrane, where it is invaginated about the lower end of the uteri.

The disposition of the slot in the forward end of the nozzle renders the complete closure of the opening in the said end by contact with the soft parts practically impossible, and the tube 6, terminating Within the shell, is consequently never so obstructed that a flow through it cannot be maintained.

Having thus described the construction and use of my invention, What I claim as new, and desire to secure by Letters Patent, is-

1. A syringe-nozzle comprising a tubular shell havingits forward end in the form of a cone, its apex disposed at one side of the axis of the shell and having the plane of its base disposed at an oblique angle to the axis of the shell, and a fixed induction-tube discharging at the apex of the cone, the interior of the shell presenting an unobstructed passage from the cone to the opposite end.

2. A syringe-nozzle comprising a tubular shell, having a keyhole-shaped slot at its forward end, and a fixed induction-tube disposed Within the shell at one side thereof and discharging at the eye of the slot, the shell presenting an unobstructed passage from the slot to the opposite end.

3. A syringe-nozzle comprising a shell having its forward end in the form of a cone with its apex at one side of the axis of the shell and its base disposed obliquely to said axis, said cone being slotted from its apex to a point in the periphery of its base, and an inductiontube discharging at the apex of said cone.

In testimony that I claim the foregoing as my own I have hereto aflixed my signature in the presence of two Witnesses.

HARRY M. CLARKE.
